To all whom oi/(1,1) OOH/13637112" Be it kuowuthat l, DANIEL 'l. Mower, u citizen of the United States oi America, re-

siding at Ann Arbor, county of /Vsshtouuw,

; wholly of motel or, if preferred, partly of motel end partly of wood.

To this end it consists in the novel construotiou, erreugement, and combination of ports hersiri shown and described, and more purtieulerly pointed out in the claims.

in the eeeompenyiug drawings, wherein. like reference ohoreetors indicate like or oorresponding ports, Figure 1 an elevation o'l my pulley, ports being broken owuy. Fig. 2 is o section token on bus 2 2 of Fig.1. Fig. 3 is e seetioutokeu on line 3 oil Fig. 1. Fig. t

is on enlarged pertiel'seetion through the riu and two uruis of o. pulley and shows one method of forming the rim oi my pulley end the manner in which the spoke ends may iii-- terloelr therewith. Fig. 5 is a pertiulseotion token on line 5 5 of Fig. l. Fig. 6 is or similar section to that shown in Fig. -l, showing or modified arrangement of the spokes and their union with the rim. Fig. 7 is a partial section token on line 7 7 of Fig". 6. Fig. 8 is u section siu'riler to blllltl? shown in Fig. l, showing the preferred manner of securing the spoke ends to the rim. Fig. 9 is a partial section when on line 9 9 of Fig. 8. Fig. 10 is e sec-- substontiellv on line 9 9 of Fig. 8, showing,' the hub in full lines. Fig. 11 is or partial section taken through the hub on line 2 2 of Fig. 1, showing a. modification. Fig. 12 is a. sectional View of oils half of a. pulley ou substantially the line shown in Fig. 1.0, broken parts of the companion half of the ulley being shown to illustrate the method oi assembling the ports; and Fig. 13 is a. partial section ol a. port of the some, enlarged, to illustrate the ottuehmerit of the arms to the rim.

in the preferred form illustrated in the tire-wines esplit or separable pulley is shown in. which the palrts may be d' ioouueoted to position the pulley on. s shaft or to remove the some therefrom without hiking" the latter out of its hangings.

As shown in all the figures, the rim 1 is of shoot molol, having its outer edges turned and boot inwardly to form it llonge or bead 2, which not only still'eus the rim, but also serves as el'l'eotive menus for securing the outer ends 3 of the arms 4 thereto. The ends 3 ol the onus are formed with beads oomplo rnouteryto the beads of the rim, adopted to be positioned in and be firmly gripped by the hood 3, whereby the ports are effectually united in melting up the pulley.

The inner ends 5 of the onus are bent outwurdly at an angle to be seated upon a hub or shell 6, to which they may be secured in any suitable manner. Thus the arms may be riveted to the shell (5, as shown in Figs. .2 and 3, or, if preferred, a. port or all of the rivets 7 may extend through the tlsniping-blocks 8, the ends 5, end shell 6 in such belt-pulley, as

shown in said Figs. 3 end ii, the hub members thus formed being edopted to be firmly secured together by bolts 9 9, uniting the clumps 8, as shown in Figs. 1, 3, 10, end. 13. It is not essential, however, that the clamp lug-blocks shall be riveted upon the shell, as their position upon the outer ends of the shell is secure when, they are bolted together, as hereinafter described. By this eonstruotion the urine, which ore also preferably of sheet or wrought motel, consist of two sets having their outer ends lirmly secured to the heed or each edge oi" the rim and thence oorwergiug both radially end tronsversely to the hub or shell, to which the inner ends are also firmly secured. This construction i lsures greet strength in the pulley. In at split pulley of course the arm-sections on eeeh side are also split or separable.

. If desired, the erm-seotions for each halfpulley maybe intogml, as shown in Fig. 11. at 5, in which the arms are bent backward upon the center web 10, leaving room within the plane of the edge of the rim of the pulley for the flange or olul'npiiur-bloo {S 8, as shown, end thence diverge to the rim edge, as before described.

To aid in securely looking the outer ends of the arms end the rims together, I prefer to roll the end of the arm outward and into the bead 2, as shown in Figs. 2, 3, 6, 7, 8, 9, and 13, and es an additional assurance of firm engugeiuent of the parts I also prefer to notch no the beedior the close reception of the ends 3 of the arm, as oleorly shown in. Figs. 1 and l,

3 eted to the rim, as shown if desired, the ends 3 of the arms may be rolled inward to engage a rod 3 1.,lirmly seated in the bond, as shown zit 3 in Figs. 4 and In this construction the bead is also notched, as shown. The ends of the arms may be simply rolled into the head. as shown at 3 in Figs.

6 and 7', or the engagement may be modified 1 by inserting arod 11 either simply at the junction of the arms with the rim, as shown, or, if preferred, by extending the rodsround the hell-pulley, as shown at 11 in Fig. 10. In the latter form I prefer to permit the end. of the rod to project, as at 12, and provide a corresponding recess at 13. By this means when the two halves of the pulley are sssembled the meeting rims will be brought into and held securel in proper registry with enchother. As shown in Fig. it), the head is crimpifrl closely 11 )On the rod, near the ends thereof, to aid in the function just described.

In Fig. 12 a similar function is preserved by securing it short section of rod 14 in each half of the pulley, Which. r-oi'iperstes with a .complemental recess 15 in the opposite hall of the ulley. The firm union of the meeting rims oFthe pulley may also be aided by providing each with half of a clamp 1d and bolting the two firmly together by one or more bolts 17. These clamps may he simplyriv to the left in Fig. 15. In the preferred construction, however, the clamps are extended and the head 2 rolled iaround the ends thereof. This may also be supplemented by rivets 18, ii desired.
